How to use a variable to act as @rule in a Sopel IRC bot module?

[arresteddevlopment at tuta.io]

Apologies for the terrible formatting, let me try that again:

A:
from sopel.module import commands, rule
import random

q_and_as = [('Why?', 'because'), ('Can I kick it?', 'nope')]

@commands("quizme")
def ask_q(bot, trigger):
     q = random.choice(q_and_as)
     bot.say(q[0])
     @rule(q[1])
     def correct(bot, trigger):
     bot.sat('Correctamundo!')

B:
...
@commands("quizme")
def ask_q(bot, trigger):
     q = random.choice(q_and_as)
     bot.say(q[0])
     answer(bot, trigger, q[1])

def answer(bot, trigger, answer):
     @rule(answer)
     def correct(bot, trigger):
     bot.say(' correctamundo!')

If the above comes out wonky again I also asked on StackOverflow 
(http://stackoverflow.com/questions/34419265/how-to-set-and-later-change-a-rule-in-a-sopel-irc-bot-module-python). 
Any help would be greatly appreciated.
